process cells. The Advanced Integrated Maintenance System (AIMS)consisting of advanced elbows-down, electronic, force-reflecting servo-manipulators with remote viewing, sound, tooling, and transportercapabilities will be capable of performing all necessary remote repairand maintenance tasks. The design of the AIMS control room, where thenuman operator interfaces with remote equipment, has been an importantaspect of the RCE activity. The design goal has been to provide a safe,efficient interaction between the operator and all AIMS equipment. Thispaper describes the five-stage method used in the development of thisdesign: mission description, design requirements, preliminary designsolution, construction, and verification of the mock-up, and refinementof the design solution.MISSION DESCRIPTIONThe authors' goal was to generate a clear account of tasks thatwould be done in the control room, the information and outputs operatorswould need to do these tasks, the characteristics of the operatorsthemselves, and the characteristics of the environment in which thetasks would be performed.;Typical remote small-volume maintenance tasks (e.g., removing a..-bolt from a metal plate) and typical large-volume tasks (e.g., unboltingand transporting a large flange) were constructed in a simulated remoteenvironment. Manipulator operators then performed the tasks under aseries of experimental conditions, providing the means to generateconcise statements about the information and controls the operator wouldneed in a hot facility control room.1'2
